摘要

The corrosion performance of various stainless steels, nickel alloys, and refractory metals has been evaluated in hot (up to 95°C) methane sulphonic acid. Studies included weight loss coupon exposure tests and potentiodynamic polarisation measurements. Also, the corrosion inhibiting effect of some inorganic inhibitors has been explored. It was found that most of the stainless steels, nickel alloys, and titanium corrode to a considerable extent, whereas Hastelloy G-30, zirconium, and tantalum withstand this environment. The addition of ferric and nitrate ions was found to produce an inhibiting effect.
